这是我的来源，Python是2.7，amd64，Ubuntu 16.04 Xenial Xerus和Xfce 4.12，PyQt4

应该显示系统托盘图标的类似内容：

self.trayIcon = QtGui.QSystemTrayIcon(QtGui.QIcon("icon.png"))

什么都不做。然而，如果使用手动trayIcon.show()在另一个.py文件上运行它可以正常工作。

你错过了节目部分：）

self.exit_button.clicked.connect(self.exit_main)

# --------------------------- QT ACTION BIND STOP ##############

self.trayIcon.show()

这对我有用

PyQt没有在XFCE / Ubuntu 16.04 Xenial Xerus
